I'm looking to setup a UK PP and I'm wondering about the best way to structure it taking into account the advantages of the tax-exempt ISA wrapper given that I have more to invest than will fit in one ISA subscription.
I'm planning on holding:
LTT: TR60.L - exempt from capital gains tax
STT: Treasury Ladder (1-3 years out) - exempt from capital gains tax
STK: HSBC FTSE All Share (OEIC Fund)
Gold: SGLN (iShares Gold ETF) - no income
1. Given that they all have slightly different tax behaviour, I thought it would make sense to fill the tax-free ISA wrapper in the order of tax exposure. If I follow this, given how much I need to invest & how much room I have in my ISAs I would end up with all my Long Term Treasuries & Stocks in the ISA, and Gold and Cash outside of it. But what if stocks have a bad year, but gold goes nuts, I may have to rebalance more into the ISA than I can legally put in in one year. (I had real problems trying to explain that, hope it makes sense!

So is it actually better to effectively have two PPs, one within an ISA wrapper, and one outside? Then all the rebalancing would occur within the ISA.
2. Given the limits of the govts. guarantee scheme it would be wise to split savings across multiple institutions. But this creates the same problem, as I imagine it's not so easy to rebalance across ISA providers. So would it be best to have multiple ISA providers, each with an individual PP structure?
Obviously this makes it more of a pain to manage and the trading charges start to magnify.
Any thoughts guys?
Thanks!
